This gist will drive you through creating a Docker 1.12 Swarm cluster (with Swarm mode) on AWS infrastructure.

Prerequisites

You need a few things already prepared in order to get started. You need at least Docker 1.12 set up. I was using the stable version of Docker for mac for preparing this guide.

$ docker --version
Docker version 1.12.0, build 8eab29e

You also need Docker machine installed.

  all = list(product('ACGT', repeat=k))
  return seq(all).map(lambda x: ''.join(x)).to_list()
  
def kmer_per_segment(dna_segment, k):
  '''return all the dna substrings of length k of the different dna strings in dna list'''
